Definition: A bullectomy is a surgical procedure to remove giant bullae from the lungs. Bullae are thin-walled, air-filled spaces in the lungs that are bigger than 1 centimeter or so in diameter.

Bullae tend to cause a worsening of dyspnea in COPD patients as they increase in size and, if they grow large enough, a bullectomy will be performed to remove them.
